perf tools: Convert to BACKTRACE_SUPPORT For building perf without stack backtrace debug, we can set NO_BACKTRACE=1 as a argument of make. It then defines NO_BACKTRACE macro for C code to do the proper handling. However it usually used in a negative semantics - e.g. #ifndef - so we saw double negations which can be misleading. Convert it to a positive form to make it more readable and add _SUPPORT suffix for consistency.

tools/perf/build: Speed up git-version test on re-make util/PERF-VERSION-GEN is currently executed on every build attempt, and this script can take a lot of time on trees that are at a significant git-distance from Linus's tree: $ time util/PERF-VERSION-GEN real 0m4.343s user 0m4.176s sys 0m0.140s It also takes a lot of time if the Git repository is network attached, etc., because the commands it uses: TAG=$(git describe --abbrev=0 --match "v[0-9].[0-9]*" 2>/dev/null ) has to count commits from the nearest tag and thus has to access (and decompress) every git commit blob on the relevant version path. Even on Linus's tree it takes 0.28 seconds on a fast box to count all the commits and get the git version string: $ time util/PERF-VERSION-GEN real 0m0.279s user 0m0.247s sys 0m0.025s But the version string only has to be regenerated if the git repository's head commit changes. So add a dependency of ../../.git/HEAD and touch the file every time it's regenerated, so that Make's build rules can pick it up and cache the result: make: `PERF-VERSION-FILE' is up to date. real 0m0.184s user 0m0.117s sys 0m0.026s Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Namhyung Kim <namhyung@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/n/tip-wvmlrurufuk6mo1ovtNigguT@git.kernel.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
